Reason for Visit: Routine
Inspection Summary:
MRO staff performed a Compliance Inspection for the Hickory Compost facility under permit WQ0004563. This is a
distribution permit for composted material that is distributed for use as a public and private Class "A" residual product.
To move the composted product, facility management has decided to give the product away for public use. The only
compost that was viewed during the site visit was the curing rows that are part of the PVAR process for the composted
residuals. This action addresses the potential issue of having bacterial regrowth when cured compost was left on the pad
in the past.
Operation and Maintenance records were reviewed during the site visit. The records appear to be complete and current.
During the site visit, it revealed that there are plans to close the facility around November 2024. MRO staff has requested
notification be provided 6 months before facility closure.
It is the understanding of the MRO that a new facility is in the planning stage for a furnace reduction treatment system to
be constructed and the Henry Fork WWTP. A permit application has not been received by the NCDEQ Non -Discharge
permitting group in Raleigh.
